The command above will insert an ascii calendar into your buffer.
Last night I was testing to see what each of the keys in the number row do when used with the Shift key in Vim. One of the most interesting

.! and places your cursor right after that.
This allows for quickly bringing in data such as the date when you are working on a blog post.
